+# PRD prd-new: Quick install script
+
+- **Status:** Draft
+- **Author:** claude
+- **Created:** 2026-07-25
+- **Issue:** #197
+
+## Summary
+
+Add a proper Python package distribution (`pyproject.toml` with a
+`bot-bottle` entry point) plus a thin `install.sh` bootstrapper, so users
+can install bot-bottle with a single command instead of cloning the repo
+and invoking `cli.py` directly. A new `bot-bottle doctor` subcommand
+verifies host prerequisites after install.
+
+## Problem
+
+There is currently no install path for new users. The only way to run
+bot-bottle is to clone the repo and invoke `./cli.py`. This blocks any
+public demo: readers want `curl | sh` or `pipx install`, not a manual
+clone-and-configure flow. There is also no single command that tells a
+user whether their host is actually ready to run a bottle.
+
+## Goals / Success Criteria
+
+- `curl -fsSL <raw-url>/install.sh | sh` leaves a working `bot-bottle`
+  command on PATH.
+- Python-native users can install with `pipx install bot-bottle` or
+  `uv tool install bot-bottle` (once published) — or from a local
+  checkout today.
+- `install.sh` validates prerequisites (Python ≥ 3.11), creates the
+  `~/.bot-bottle/` config tree, installs the package, and runs
+  `bot-bottle doctor`. It never installs Docker or a VM backend silently
+  and never uses `sudo`.
+- `install.sh` is idempotent — safe to re-run.
+- `bot-bottle doctor` reports Python version, backend *readiness*, and
+  config-dir presence, exiting non-zero when a hard prerequisite is unmet.
+- The package keeps **zero runtime pip dependencies** (stdlib-only,
+  matching the existing constraint in `AGENTS.md`).
+
+## Non-goals
+
+- Bundling a Python runtime or producing a standalone binary.
+- Automatic Docker / VM-backend installation.
+- Plugin-architecture changes (issue #197 floats a containerized-plugin
+  direction; that's a separate feature).
+- Publishing to a package index in this PR — the package *structure* is
+  the deliverable; publishing is a follow-up step.
+
+## Design
+
+### Package structure (`pyproject.toml`)
+
+Fill out the previously-stub `pyproject.toml` with project metadata, a
+console-script entry point, and package-data for the non-Python assets the
+runtime reads from inside the package:
+
+```toml
+[project]
+name = "bot-bottle"
+version = "0.1.0"
+requires-python = ">=3.11"
+dependencies = []
+
+[project.scripts]
+bot-bottle = "bot_bottle.cli:main"
+```
+
+`bot_bottle.cli:main` already exists (the `cli.py` shim calls it), so no
+refactor of the entry point is needed. `package-data` ships the non-Python
+assets that live *inside* the package (`egress_entrypoint.sh`, the contrib
+Dockerfiles, the firecracker netpool defaults, the macos-container init
+script).
+
+### Self-contained wheel (build resources)
+
+The gateway / infra / orchestrator images are built from a Docker (or Apple
+`container`) build context that must contain the `bot_bottle` package,
+`pyproject.toml`, and the **root-level** Dockerfiles as siblings. Several
+modules used to locate that context by walking `__file__`'s parents to the
+repo root (`_REPO_ROOT = Path(__file__)…parents[N]`) and reading
+`Dockerfile.gateway`, `nix/firecracker-netpool.nix`, and
+`scripts/firecracker-netpool.sh` from it. In an installed wheel the package
+lives in `site-packages` with no repo root above it, so those reads fail —
+`doctor` passes but `start` / backend setup breaks.
+
+Fix: a single resolver, `bot_bottle/resources.py`.
+
+- `build_root()` returns a directory shaped like a repo root (has
+  `bot_bottle/`, `pyproject.toml`, the Dockerfiles, `nix/`, `scripts/`).
+  In a **checkout** it's the repo root itself — unchanged behavior. From an
+  **installed wheel** it stages a copy under the app-data dir, keyed by a
+  **content digest** of the installed package + bundled resources (not the
+  distribution version): the installer defaults to a git branch and
+  `pipx install --force` while `version` stays `0.1.0`, so a version key
+  would reuse a previous commit's tree — the digest key re-stages instead.
+  Staging is concurrency-safe: a file lock serializes it, each writer builds
+  into a private temp dir, and the finished tree is published with an atomic
+  rename (never populating a shared path another process might read).
+- The root-level resources are shipped inside the wheel under
+  `bot_bottle/_resources/` by a `setup.py` `build_py` step (kept in sync
+  with `resources.BUNDLED_RESOURCES`); `MANIFEST.in` includes them in the
+  sdist.
+- Every former `_REPO_ROOT` / `_REPO_DIR` call site now derives from
+  `resources`: the docker/macos agent-image launch, each backend's
+  `orchestrator` / `gateway` / `infra` service, firecracker `infra_vm` /
+  `infra_artifact` / `setup`, and the shared `gateway` build context. So
+  checkout and wheel installs share one downstream path.
+
+Verification: `test_resources` exercises both layouts — including the staged
+wheel context, a re-stage when package content changes at the same version,
+and a rebuild of a partial (crashed) stage. `test_wheel_install` builds the
+wheel, installs it into an isolated venv, and asserts `bot-bottle doctor`
+runs and `build_root()` produces a valid context; `build` is in
+`requirements-dev.txt` so it runs in CI, and a build/install failure fails
+the test (it does not skip). Running `start` end-to-end still needs a
+Docker/KVM host (CI), not a source checkout.
+
+### `install.sh`
+
+A POSIX `sh` bootstrapper that:
+
+1. Checks `python3` is present and ≥ 3.11; exits with a clear message
+   otherwise.
+2. Checks `git` when installing a `git+` spec, and — when falling back to
+   pip — that pip is usable and the interpreter isn't externally managed
+   (PEP 668), pointing at pipx otherwise.
+3. Creates `~/.bot-bottle/{agents,bottles,contrib}`.
+4. Installs via `pipx` if available, else `python3 -m pip install --user`.
+   The spec defaults to the git URL and is overridable via
+   `BOT_BOTTLE_INSTALL_SPEC` (used by tests / local installs).
+5. Locates the `bot-bottle` entry point: PATH first, else the
+   interpreter's own user-scheme scripts dir resolved via `sysconfig`
+   (`~/.local/bin` on Linux, `~/Library/Python/<X.Y>/bin` on a python.org
+   macOS interpreter — not hardcoded).
+6. Runs `bot-bottle doctor` and reports the result.
+
+It is idempotent and never calls `sudo`.
+
+### `bot-bottle doctor`
+
+A new store-free subcommand (no DB migration required) that checks and
+reports:
+
+- **python** — interpreter version (hard requirement: ≥ 3.11).
+- **backend** — at least one backend *ready* on this host
+  (macos-container / firecracker / docker), via `is_backend_ready()` — a
+  full backend `status()` probe (daemon reachable, network pool present,
+  KVM usable), not a PATH-only check: a stopped daemon or half-configured
+  backend must not report `ok` when `start` can't work. Each not-ready
+  backend prints its own diagnostics. Hard requirement.
+- **config** — whether `~/.bot-bottle/` exists (advisory only; `start`
+  provisions on first run).
+
+Exits 0 when both hard requirements pass, non-zero otherwise.
+
+## Testing strategy
+
+- Unit test `bot-bottle doctor` success/failure paths with backend
+  readiness (`is_backend_ready`) and Python version mocked, including the
+  available-but-not-ready → fail case.
+- Unit test that `pyproject.toml` parses, declares the entry point and an
+  empty `dependencies` list, and that every `package-data` glob resolves
+  to a file that exists on disk (guards against drift).
+- Unit test that `install.sh` is executable, POSIX-ish (`set -eu`), never
+  calls `sudo`, and runs `doctor` after install.
+
+## Open questions
+
+- Should `version` be derived from a git tag at build time (e.g.
+  `hatch-vcs`) or kept static? Static (`0.1.0`) is simpler for now.
+- Publishing target (PyPI vs. a self-hosted index) is deferred.
